Correct option is C
(A) is true but (R) is false
Activity-based teaching-learning is considered child-centered (A) because it focuses on engaging students actively in their learning process, catering to their interests and needs. However, the assertion that teachers do not play any role in the teaching-learning process (R) is false. Teachers are integral to activity-based learning, as they design and facilitate activities that are educational, engaging, and suitable for the students' developmental levels. They guide, support, and challenge students, making learning more effective. The role of the teacher in this approach is transformative rather than passive.
